Application filed January 6, 1906, Serial No. 294,936.

'ment in bracelets, and more particularly to an improvement in concealed hinges for bracelets.

,The object of my invention is to improvethe construction of a concealed hinge for bracelets, whereby the construction of the hinge is simplified and the cost of manufacturing the same reduced. v

A further object of my invention is to provide a bracelet with a strong and durable concealed hinge having a limited opening movement.

My invention consists in the peculiar and novel construction of a concealed hinge for bracelets, with details of construction, as will be more fully set forth hereinafter.

Figure 1 is a side view of-a bracelet provided with my improved concealed hinge and showing the bracelet in the closed position in full lines and in the open position in broken lines. Fig. 2 is an enlarged detail sectional view of the hinge end of the bracelet looking at the outside face of the hinge, Fig. 3 is an enlarged detail sectional view taken on line 3 3 of Fig. 2 and showing the hinge in the closed position. Fig. 4 is an enlarged detail sectional view similar to Fig. 3, showing the hinge in the open position. Fig. 5 is an enlarged detail edge view of one of the hinge members, and Fig. 6 is an enlarged detail view of the other member of the hinge looking at the inner face of the same.

In the drawings, d indicates one semi-oval half, the other semi-oval half, and f the improved concealed hinge of the bracelet. The semi-oval halves d and e are constructed from a tube which is oval in cross-section. The half (1 has the end (1 for the hinge f and the end (1 The half e has the end 6 for the hinge f and the end 6 The ends (1 and e and the ends d and e coincide whenthebracelet is closed. The ends d and' 6 may be provided with any one of the well-known forms ofcatches adapted to hold the ends together when the bracelet is closed.

My improved concealed hin e f consists of a solid member 9 and a tubu ar member h.

These members 9 and h are curved to con' form to the contour of the bracelet and shaped I to fit in the ends (1 and e of the halves d and e. The member 9 of the hinge is constructed to have a solid body portion g, from one end o'o of which extends a central arm g having a curved portion 9 merging into a hook-shaped end g, as shown in Fig. 5. The inner concave face 9 and the outer convex face 9 of the curved portion 9 is struck from a center 6i; p

which is concentric with the center on which the hinge opens, as shown in Fig.4. The

tubular member it has a hollow body portion h, an open end 72?, and a closed end its, in.

which is a rectangular opening 7% the width of which coincides with the width of the central arm g on the member g, and a transverse stop-pin 721 which extends through holes adjacent the closed end of the member h across the opening h, as shown in Figs. 2 75 and 6, where it is secured by upsetting the ends of the pin in the member or by other means. The side edges hf h of the opening h in the member h are adapted to bear on the sides of the arm 9 on the member g, the outer 8o edge h ofthe opening on the inner concave face 9 of "the arm 9 and the inner edge k of the opening on the outer convex face 9 of the arm 9 as shown in Figs. 2, 3, and 4.

The hinge is assembled by placing the central arm 9 on the member 9 in the-opening k in the member h in a position for the sides h h of the opening to engage with the sides of the arm. 9 the edge 7L7 of the opening to engage with the inner concave face 9 of the arm and for the edge h of the opening toengage with the outer convex face g of the arm. The pin k is now driventhrough the holes in the member h over the concave face g of the arm 9 and secured in the member h.' The 5 members 9 and h of. the hinge are now forced into the ends (1 and e of the bracelet into a position where the center on which the hinge opens coincides with the juncture of the ends (1 and e of the bracelet. g and h ofthe hinge members are now secured in the ends (1 and c of the bracelet by solder or other means. When the bracelet is closed, a space is formed between the stoppin 7L5 and the hook-shaped end g of the arm IO 5 9 as shown in 3, which allows for a predetermined opemng movement of the bracelet, and this opening movement of the bracelet is limited by the hook-shaped end 9v on the arm 9 engaging with the stop-pin k on no the member h, as shown in Fig. 4. The stoppin' k engaging with the hook-shaped end The body portions I00 g, also prevents the separation of the hinge members after the same have been assembled.

Having thus described my invention, I

having a curved portion merging into a hook shaped end, the inner concave face and the outer convex face of the curved portion being struck from a center which is concentric with the center on which the hinge opens, and a tubular member having a hollow body por tion, an open end, a closed end in which is a rectangular opening into which the central arm of the solid hinge member extends, and a stop-pin which extends across the inner concave face of the central arm on the solid Lnember and is secured in the tubular mem- 2. A concealed bracelet-hinge comprising a member 9 having a solid body portion g from one end of which extends a central arm g having a curved portion 9 merging into a hook-shaped end 9 the inner concave face 9 and the outer convex face 9 of the curved portion g being struck from a center which is concentric with the center on which the hinge opens, and a tubular member it having a hollow body portion it, an open end 7L2, a closed end 7L3 in which is a rectangular opening h formed by the side edges 7L 7L, the edge 71 and the edge its, a stop-pin 71: which extends across the inner concave face of the central arm 9 and is secured in the tubular member 7L.

8. The combination with a tubular half (Z having the end d and a tubular half 6 having the end of a bracelet, of a concealed hinge f composed of the members 9 and 72 the member g having a solid body portion g from one end of which extends a central arm g, having a curved portion g merging into a hookshaped end 9 the inner concave face 9'' and the outer convex face g of the curved portion g being struck from a center which is concentric with the center on which the hinge opens, and the tubular member it having a hollow body portion h, an open end It, a closed end ha in which is a rectangular opening 7L formed by the side edges h h, the edge 72,7 and the edge if, a stop-pin h which extends across the inner concave face g of the central arm 9 and is secured in the tubular member h, and means for securing the members g and h of the hinge in the ends d and c of the bracelet, as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
